## 下载 redis.conf
下载地址：[https://github.com/antirez/redis/blob/unstable/redis.conf](https://github.com/antirez/redis/blob/unstable/redis.conf)
## 修改 redis.conf
开启集群功能：
`cluster-enabled yes
`
设置节点端口：
`port 6391
`
节点超时时间，单位毫秒:
`cluster-node-timeout 15000
`
集群内部配置文件:
`cluster-config-file "nodes-6379.conf"`
## 编写 docker-compose.yml
## 编写 redis 默认的启动脚本 创建文件 `config/redis.sh` ``` redis-server /config/nodes-${PORT}.conf ``` ## 启动集群 `$ docker-compose up -d ` ## 初始化集群 (>redis5.0 ) 创建 3 主 3 从的 redis 集群： ``` $ redis-cli --cluster create 192.168.99.100:6391 \ 192.168.99.100:6392 192.168.99.100:6393 \ 192.168.99.100:6394 192.168.99.100:6395 192.168.99.100:6396 \ --cluster-replicas 1 ``` ## 连接 redis ``` redis-cli -h 192.168.99.100 -p 6391 ```
